Reinforcement structure for cross beam of auxiliary frame of motor vehicle, has passage connected to wall of frame element extending by formed hollow space and firmly connected with adjacent wall in connection area

摘要

The structure has a set of frame elements (7a, 7b) firmly connected with one another in boundary regions. A pot-like passage (9a) is formed in walls (8a, 8b) of one of the frame elements for increasing rigidity and firmness of a hollow section-like carrier (2), where the passage is connected to adjacent walls of the other frame element extending by the formed hollow space and is firmly connected with the adjacent wall in a connection area. The walls of the frame elements have boreholes that are coaxially arranged to each other.
